To allgfwhom 'it may coacer'm Be it known that I, SEYBERT D. FENrMonE,a. citizen of. the United States, -residing at Folcroft, in the countyof Delaware v'and State ofPennsylvania, have invented certain new 'anduseful Improvements in Trolleyf Poles, of which the following is aspecification, 'reference being had to the accompanyi inddrawings.'

y invention relates to improvements in trolleys' and consists ofthen'ovel features of construction and the combination and arrangementof parts hereinafter described The object ofthe invention is to providea device of this character by which tne trolley wheel will be heldfirmly in contact with the trolley wire and at the Sametime prevent itfrom dying-up and striking the cross arms that support the trolley wire,when the wheel jumps the wire.

l Another vobject of the invention is to pro.-l vide a trolley pole withan operating rope which Vwill be drawnltaut and prevented 'from hangingslack and which will also limit the upward .swinging movement of thepole` when the wheel leaves the wire. 'lhe above and other objects ofthe invention, which w,ill appear as the nature of the invention isbetter understood, are attained 1n its preferred embodiment .illustratedin the accompanyingdrawing's, .in which Figure 1 is a side'elevatlon ofmy .im-2

proved -trolley pole showing the same in use; Fig. 2 is a detailvertical longitudinal er portion o section taken through the up f thedevise and on an enlarge scale; Fi 3 is a tfp Flan view of the partsshown in 4`ig. 2; an ligs. 4 and 5 are transverse sections taken,respectivelyfon the planes indicated by the lines 4-4 and 5-5 in Fig. 2.

In the drawings, 1- denotes a portion of a car and 2 a spring pressed,pivotall mounted trolley pole. The latter may-bel o any suitable formand construction and has upper and lower sections 3, 4 connected by a hme or knuckle joint 5. This joint is prefere ly formed by reducing theupper end of the lower section 4 to provide a .ton ue 6. and squareshoulders 7 o n opposite siesof the latter, and by' recessingl the lowerend of the 'upper section to'- receive said tongue and The ro e 21.h'as1tslower of the' section and the tongue 6 to pivotally unite the twosections so that the upper sect-ion can swing upwardl to an angularposition with respect to the ower section 4. The upper section S-of thetrolley pole is comparatively short and carries a trolley wheel 10 whichmay be 'of any Asuitable form and construction land mounted ina'nys'uitable manner. As illustrated itis grooved to en- 1gn Iiheforked4 upper end 1270i said pole .section3.

When the trolley wheel is engaged with the Wire 11 the shoul'ders, 8engage each other and the two pole sections are inllongitudinalalineinent, but when the wheel leaves the' wire or 'when the tensionexerted actuating springs of tlr'lnwer sei-.tion

by the l 4 isremoed from said section, the'upliier section 3 shown inFig. 2 by a coil spring 123 arranger between a combined guide and stop'lug 11 onthe sec-tion 2 and a stop lug 15 on the section 3. The spring13 surrounds a rod 16 whichfhas its upper end lined to the lug 15 andits 'lowervend projecting through an aperture in -the lug 14 andivotaly' or loosely connected to a piroted og or clutch 17 by passingsaid end of the rod through a flared aperture inthe dog-and then headingor upsetting 'said end. The dog is piyoted at its upper end as at 18 ina recess ilrthe collar 19 which is fixed upon the pole section 4. Alsoarranged in the recess insaid collar b19 is a fuide pulley 20 for thecord, rope or otherexible element- 21 by means of which the trolley poleis raised and lowered: end fixed to the car an f its other end passingthrough the recess in the collar 19 over the pulley 20 and beneath the'clutch 17, and attached to a weight 23 which is slidably mounted uponthe pole 2 and provided for the purpose of holding said rope taut. Theweight 23 has an open portion 24 to loosely receive the section 4 of thepole and in the top of this open portion are journaled one or morerollers 25 which. areV adapted to run upon` the top of the section 4 andallow the wei ht to'slide easily thereon.- It will be seen t at theprolvision of the weight 23 causes the trolley cord to be always drawn,taut and prevents it from hanging slack and being in .the way at thesame time the pole is permitted to have free Swingin movement. The frontand lower corner o the upper portion of the ave the trolley wirev 11and, it is journaled` is swung to its angular position weight 23 isbeveled as shown at 23" so that should for any reason the device fail tooperate as above explained, the weight vwill not offer any seriousobstruction to any brace'wire, cross arm,'or the likewhich may be in thepath ofthe pole, since said beveled portion will allow such wire or armto slip over the weight.

The arrangement of the dog or clutch 17 and its connection to the rod 16is such that when the trolley wheel is engaged with the wire 11 and thetwo pole sections are in alinement the clutch 17 will be held out'ofcontact with the rope so that itmay pass freely back and forth over thepulley 20, but the instant the wheel leaves the trolley wire and ltheupper section 3 swings to an angular position the rod 16 will actuatethe clutch and cause its free end to press the rope against the pulley2O and thus. clamp the rope and prevent `the. trolley pole from polesection and passing through knl'ickle'join't, a. lug

swin ing vupwardly into the path of the usua wire. Thus it will be seenthat the Jinstant the wheel leaves the wire the rope will be clutchedand the pole prevented from swinging upwardly.

Having thus described my invention what I claim is;

1. The combination of a trolley pole having upper and lower sectionsconnected by a projecting from the upper section, an apertured guide lugprojecting from the lower section, a collar upon the lower sectionprovided with a recess, a pulley` journaled in said recess in thecollar, an

voperating rope engaged with said ulley, a

dog pivoted at its upper end in said recess in the collar above thepulley and having its .free lower end formed with a clutch Vsurface toengage the rope passing over said-pulley,

a rod connected to the lug upon the upper the aper- 'and looselyIconnected crossarms which support the trolleyand loosely ture in the lugupon the lower pole section to the intermediate portion of said dog, acoil spring surrounding said rod and confined between the two lugs uponthe upper and lower pole sections and rope.

ing upper and lower sect-ions, the lower section having its oppositesides recessed to provide a central tongue and stop shoulders, the uppersection having its adjacent end recessed to receive said tongue andbeveled to provide stop shoulders to engagethose on the lower section, atransverse pivot passed through said sections to pivotally unite themfor a limited swinging movement, a lug upon the upper section, anapertured lug upon the lower section, lower section'and provided with arecess, a guide pulley journaled in the lower portion of the recess inthe collar, an operating rope passed over said pulley, means fo'r takingup the slack in saidrope, a-dog pivoted at its upper end in the upperportion in the colla'r and having its shaped to provide a clutch face(rages the ropeupon the pulley, the intermeldiate portion ofsaid dogbeing formed with an opening, a rod fixed at one end to the lug upon theupper pole section' and having its lower portion passed through theaperture in the lug upon the lower pole section secured in the aperturein the dog, and a coil spring surrounding said rod an lower end whichen- 2.,The combination of al trolley pole hav.

a collar upon v the' means for taking up the slack in said of the reces' I confined between the lugs upon the two pole sections, substantiallyas described.
